Dear all,

The problem is to

create parameters. At this time, I  successfully create a function call
with two constante as parameter and insert it (I can see that in the
asm's code). But, I want to give the address of an array and a constante
to this function.
I think the problem is the creation of the node which contains the
address of the array.

For example:
I get from the code (in tree rhs):
a[i]
I want build a node like that:
a[i]
and build a function call like that:
foo(constante,a[i])

This is the error message when a try to compile a program with my pass :

Can you send a backtrace?

This means nothing has created the variable annotation for a.

Hi,

My version of gcc:

version gcc 4.3.0 20070316 (experimental)

I try to do a backtrace with gcc but the program exit normally. So, I 
try to put a breakpoint but :


(gdb) b tree-flow-inline.h:1629
No source file named tree-flow-inline.h.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (tree-flow-inline.h:1629) pending.

I'm sorry but I can't show you a backtrace. (I do compilation with 
option -g)

How I can put a breakpoint ?

Are you debugging gcc or cc1?
you need to be debugging cc1

(use -v with your compiled gcc to get the cc1 command line it uses,
and just run gdb --args cc1 command line it is using

 Thanks for any help in finishing this pass

See how omp-low.c builds calls to the child parallel functions
(create_omp_child_function).

Re: Creating parameters for functions calls

[Antoine Eiche]

Thx for your answer,

But I believe the problem is not the contruction of the parameters of 
the function, but the construction of the adress of an array and give it 
at a function call.

Maybe, I don't say good my problem in my previous mail.

Example:
If I have an array A in a source code, I want to create the address of 
this array and to give it at a  function which I have insert:


main{
int A[10];
int b;
...
...

foo(  A[2]);  //This is the statement that I want to insert

b=A[2];
...
...
}

I make clear that I  success in doing:
main{
int A;
int b;
...
...
b=A;

foo(  A);
...
}

How  can I to build this statement ?

Sorry for my bad english ( if it is not comprehensible, tell it me ! ),
Thanks in advance,

Antoine
